I recently came across Kojo at the Scala blog and has played around with it. It's really an excellent tool for play and learning! I will try to introduce it to my bothers son. What is an appropriate age starting to use Kojo?
Is there any chance of introducing animation of 2D or 3D models with connections, movement, and forces like gravitation and magnetism?
Is it possible to use a more full featured IDE, like Eclipse, with Kojo?
